T 0 all whom it may concern:

Be it known that I, CHARLES B. BELKNAP, a citizen of the nited States,residing in the city of Detroit, county of Wayne, and State of Michigan,have invented certain new and useful Improvements in DishwashingApparatus, of which the following is a specification.

This invention is an improvement on a similar invention filed as anapplication April 16, 1919, in the name of Jane T. Belknap, the latterbeing issued as Letters No. 1,345,059, June 29th, 1920.

This invention relates to improvements in dish washing apparatus and hasamong its salient objects to provide a construction in which the dishesor utensils beingwashed are simultaneously bodily reciprocated androtated in a cleansing fluid; to provide aconstruction in. which theutensils being washed are placed in a rack or 'cage detachably mountedon a constantly reciprocating and rotating spindle or shaft,'wherebysufiioient agitation of the cleansing fluidis obtained to thoroughlyclean said utensils, and to pro-- vide a construction which is devoid ofparts difiicult to clean or complicated in operation and one in whichthe water for cleansin or rinsing may be maintained at any desiredtemperature.

The important feature of this invention is the particular type ofdriving shaft used in connection with. this d'sh washing apparatus.

In the drawings Figure 1 is a vertical side elevation, partly insection, of the improved device.

Fig. 2 is a plan view of the rack or cage. Fig. 3 is a detail view ofthe reciprocating mechanism.

Referring to the drawings-1 designates a suitable frame on which ismounted a water-tight tank 2 provided with a cover 3. The tank, which ispreferably of cylindrical shape, is provided with a centrally disposedvertical extending sleeve 4: having watertight bearings 5 and 6. Inthese bearin is rotatably mounted a shaft or spindle the upper end ofwhich projects through the caring 6 and is squared to receive the hub 9of the dish rack 10. Handles 10 are fitted on the,.edge of the rack tofacilitate its removal from thetank 2. This rack- 10 is provided with aplurality of removable baskets 11 mounted one above the other, thebaskets bemg divided, as shown, to receive plates,

cups, glasses, silverware and the like. It is, of course, apparent that,as the shaft is rotated and reciprocated simultaneously, the rack orcage 10 will revolve within the tank and be raised and lowered with thereciprocation of the sleeve 4.

Describing now the manner of actuating the shaft 7-this shaft is in twoparts joined by a tongue and groove connection as shown at 13, the lowerend mounted in a lower hearing 12 the upper section of the shaft havinga bifurcated lower end 14.- fitting over the vertical tongue 15 of thelower section 7. Through the upper section. of the shaft 7 extends atransverse pin 16 having rotatable ends which are adapted to roll in aslotted passage or groove 18 cut in a sleeve 19, the latter beingfixedly mounted upon a bracket 20 riveted or bolted to the frame 1. ofthe ap aratus. Screw plugs 20 are fitted in ho es in the sleeve andfurnish a means for removing the pin 16 from the vertical shaft. On themounted a worm gear 21 meshing with a similar gear 22 mounted upontheshaft 23 to which power is supplied from any suitable source (notshown). The rotation of the shaft 23 being transmitted to the verticalshaft by the worm tion to the rack containing the utensils to becleaned. The reciprocatory movement is produced by the travel of thetransverse pin 16 in the cam slot or groove 18 cut in the sleeve 19.

The'tank 2 is 'filled with hot water and cleaning fluid, which may beheated by a burner 24: to any desired temperature. Suitable suds, ofcourse, use of soap or like substances.

As the shaft 7 is reciprocated and rotated, suilicient agitation of thewater will be obtained to thoroughly and uniformly clean the utensils inthe rack. After the dishes or utensils have been washed, the soapy wateris drawn oil through a valve 25 and the utensils cleaned with rinsingwater, which may also be drawn off through the same valve. By thismanner of washing and rinsing the dishes, I am able to subject them tosuflicient heat to thoroughly sterilize them, which cannot beaccomplished where the dishes are washed by hand, as the completesterilization of the dishes is not possible" unless the water is atsubstantially boiling point.
